Help Jordan Save Ziggy's Life

My names Jordan, pictured is Ziggy. I’ve had my baby for 2 months now, I rescued him off the streets when he was a month old. He is the most playful energetic cat i’ve ever known. He is so full of curiosity, of love. He cuddles me every night and wakes me up with kisses in the morning. I love him with my whole heart. Yesterday I got home and he wasn’t breathing right. He has very rapid, shallow breathing. I took him to the emergency vet, and then to my primary care provider for a second opinion. They did an exam and said it doesn’t look good. To start his treatment plan they say he needs, VetScan Comprehensive Diag Prof+CBC pre surgical, Idexx Feline ProBNP Snap Test, FeLV/FIV Test, Chest Xray Study-AIS Radiology Interpretation, all of which is going to cost $1,527.29. I know this is a long shot. I’m 23, I make minimum wage, no outside financial support. If this doesn’t work i’m going to have to try to find someone with money to adopt him because I can’t do nothing. Please help me help Ziggy. I don’t want to lose him.
